Q.

Name the end products of aerobic respiration.

2. Water and energy

3. Sugar and oxygen

4. Carbon dioxide and energy

Q.

Dark reaction in photosynthesis is called so because

2. It occurs more than rapidly in night

3. It can also occur in darkness

4. It cannot occur during daytime

Q.

What are end products of aerobic respiration?

Q.

During fermentation, pyruvate is converted into carbon dioxide and G. In our muscle cells during vigorous exercise pyruvate is converted into H. In mitochondria, it is converted into carbon-dioxide and I. The fermentation process in yeast is also called J while that in mitochondria is referred to as K.

Q.

Glucose is oxidized to produce ethyl alcohol or lactic acid during the process of:

1. Breathing

2. Anaerobic respiration

3. Combustion

4. Aerobic respiration

Q.

Is glucose a reactant in the aerobic stages of cellular respiration?

Q.

Mention the end products of respiration

2. False

Q. During the process of gaseous exchange in the alveoli, what kind of movement of gases can be observed?

1. Oxygen is inhaled and directly passed to the blood for the exchange
2. Carbon dioxide diffuses in and oxygen diffuses out.
3. Carbon dioxide diffuses out and oxygen diffuses in.
4. None of the above.

Q.

Which of the following statements about anaerobic respiration in plants is not true?

Q.

Question 17
When we breathe in air, nitrogen also goes inside along with oxygen. What is the fate of this nitrogen?

(a) It moves along with oxygen into the cells
(b) It comes out with the $C{O}_2$ during exhalation
(c) It is absorbed only by the nasal cells
